Patent DE-3228202-A1 (DE)
IPC: B23K3/04
Filed: 1982-07-28
Abstract: In a circuit arrangement for controlling the operating temperature of the heating coil of an electric soldering iron, the resistance variation of the heating coil itself is to be evaluated at lowest possible cost of circuitry and doing away with a thermocouple sensor that used to be arranged in the region of the soldering bit or of the heating coil, at high mechanical cost. To this end, a precision resistor is inserted in the heating circuit and a TRIAC switching element connected between the latter and the heating element, which is switched open by a comparator circuit as a function of the voltage drop at the precision resistor or which lets through only the pulses of a pulse generator circuit required for measuring the switch-on threshold, which pulse generator circuit is synchronized via a null detection circuit for null passage of the AC voltage. The voltage drop is further compared with a preset voltage and when it is reached an integration capacitor is charged, the voltage of which controls the comparator in proportion to a reference voltage. The TRIAC is switched on as long as the voltage at the output of the integration exceeds the reference voltage, and is switched off as long as this voltage is lower than the reference voltage. In the latter case the integration capacitor forms a time function element for the reheating of the heating coil.

Title: Process for producing a fuse body having at least one contact ring embedded in it in a contour-flush manner
Inventor: HEIGL MANFRED
IPC: F42C19/07
Filed: 1983-07-30
Abstract: To produce exact contour-flushness between a fuse body and at least one contact ring embedded in it, especially by using the injection-moulding method, a contact ring, the contour of which corresponds to the inner face of the top part of the injection mould, is introduced in the correct position, so that the injection-moulding material of the fuse body can be injected between the mould top part and mould core. This cost-effective process is characterised by a very high reproducibility in respect of the contour-flushness between the fuse body and the contact ring embedded in it and also meets the high requirements of thermal and mechanical loading capacity of the contact ring embedded in the fuse body.

Title: Peak value rectifier
Inventor: HIMMLER ROLAND DIPL ING
IPC: G01R19/04
Filed: 1983-09-06
Abstract: The invention relates to a peak value rectifier for RF applications, using transistors. The task of rectifying very small alternating-voltage signals with high temperature stability, without DC offsets and without having to take into consideration diode threshold voltages, is achieved by forming two branches, the peak value being present in one branch and the mean value being present in the other branch. A differential amplifier then forms the difference between these two branches and outputs a signal proportional to the peak value to the output.

Title: Lorry with a motor vehicle and a trailer connected via a trailer coupling
Inventor: LEUKEL ROLF
IPC: B60D1/40
Filed: 1984-04-25
Abstract: The invention relates to a lorry with a motor vehicle, which is equipped with a trailer coupling, and with a trailer which is provided with a fork which has a coupling ring. The trailer coupling and the fork of this lorry are to be developed in such a way that engagement of the coupling can occur by the motor vehicle reversing without people being present in the hazardous coupling region. This is achieved in that the trailer coupling is provided with a fixing bolt which protrudes upwards at least before the actual coupling process and in that the fork of the trailer is provided with a telescopically extendable linkage arrangement whose linkage element which can be extended furthest is provided with an eye which can be guided via the fixing bolt. In this way, the fork of the trailer can be positively aligned with the trailer coupling by means of the linkage arrangement, both in respect of the height and also in respect of the lateral direction of the said trailer coupling so that, now, when the motor vehicle reverses, the coupling ring of the fork is automatically guided into the catch mouth of the trailer coupling.
